Biomedical Parameters Monitoring System for the Diagnosis of Sleep Disorders

Abstract

A biomedical parameters monitoring system for the diagnosis of sleep disorders provides a plurality of sensors reading a series of biometric parameters, one or more external devices collecting the data read by the sensors for making the diagnosis, and a facial support on which at least one sensor is mounted for reading the electroencephalographic signal and the electrooculography signal and a sensor for reading the electromyographic signal; the facial support has a central part, suitable for being located at the mouth and the nose, on which a sensor is mounted to read the respiration rhythm and the emitted carbon dioxide signal; each of the sensors is provided with a radio transceiver to transmit the reading data to said one or more external devices. The result is a monitoring system without wiring and efficient from a diagnostic point of view.
